I now discharge my promise, and compete my design, of writing the History of United States Naval Operations in World War II. Eighteen years have elap… - Samuel Eliot Morison

Exploring American History has been a very absorbing and exciting business now for three quarters of a century. Thousands of graduate students have produced thousands of monographs on every aspect of the history of the Americas. But the American reading public for the most part is blissfully ignorant of this vast output. When John Citizen feels the urge to read history, he goes to the novels of Kenneth Roberts or Margaret Mitchell, not to the histories of Professor this or Doctor that. Why? American historians, in their eagerness to present facts and their laudable concern to tell the truth, have neglected the literary aspects of their craft. They have forgotten that there is an art of writing history.

And in this flight of history from literature the public was left behind. American history became a bore to the reader and a drug on the market; even historians with something to say and the talent for saying it (Henry Adams, for instance) could not sell their books. The most popular American histories of the period 1890–1905 were those of John Fiske, a philosopher who had no historical training, but wrote with life and movement.

It was a very costly war to both sides. The Germans reckon that they lost 32,000 submariners from 781 U-boats. They and the Italian submarines sank 2828 Allied and neutral merchant ships of 14,687,231 tons, together with 158 British Commonwealth and 29 American warships, several warships of other nations, and a very large number of aircraft. The loss of life at sea that the U-boats and Luftwaffe inflicted on the Allies has only been computed for the British merchant marine, which alone lost 29,994 men to enemy action. Hardly less than 40,000 men, and several hundred women and children, went down into the depths as a result of enemy submarine and aircraft attacks. The Atlantic, which since the dawn of history has been taking the lives of brave and adventurous men, must have received more human bodies into its ocean graveyard during the years 1939-1945 than in all other naval wars since the fleets of Blake and Van Tromp grappled in the Narrow Seas.
